The table shows a meteorologist's predicted temperatures for an April day in Washington D.C. Use quadratic regression to find a quadratic model for this data. (Use the 24-hour clock to represent times after noon.)

–0.007x^2 + 15.907x – 40.131
–0.507x^2 + 14.907x – 36.131
–0.507x^2 – 14.907x + 36.131
–1.007x^2 + 13.907x – 32.131
